Which is the least electronegative element?

ALithium
Correct Answer
BCarbon
CBoron
DFluorine

Solution

Electronegativity is the tendency of an atom to attract electrons towards itself.
As we move from left to right in a period electronegativity increases as we move from metals to non metals.
$$ Li < B < C < F$$
Hence, lithium is least electronegative.
